Failure-mode index

Search what already failed

A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.

WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Aβ plaques do not protect against HSV‐1 infection in a mouse model of familial Alzheimer's disease, and HSV‐1 does not induce Aβ pathology in a model of late onset Alzheimer's disease

Olga V. Bocharova, Aidan Fisher, Narayan Pandit et al. · 2022 · Brain Pathology

The possibility that the etiology of late onset Alzheimer's disease is linked to viral infections of the CNS has been actively debated in recent years. According to the antiviral protection hypothesis, viral pathogens trigger aggregation…

Imaged-guided focused ultrasound in combination with various formulations of doxorubicin for the treatment of diffuse intrinsic pontine glioma

Rianne Haumann, John Bianco, Piotr Waranecki et al. · 2022 · Translational Medicine Communications

Abstract Background Diffuse intrinsic pontine glioma (DIPG) is a notoriously difficult tumor to treat, with an overall survival of DIPG patients being only 11 months. One of the major obstacles for the effective treatment of DIPG is the blood–brain barrier (BBB). In order to circumvent the BBB, drug delivery methods are needed that target the pontine area. One such approach is microbubble-mediated focused ultrasound (FUS)—a non-invasive method that can temporarily and locally open the BBB. Previously, it was shown that FUS is safe with minimal side effects and rapid recovery times in preclinic

Practice of oxygen use in anesthesiology – a survey of the European Society of Anaesthesiology and Intensive Care

Martin Scharffenberg, Thomas G. Weiss, Jakob Wittenstein et al. · 2022 · BMC Anesthesiology

Abstract Background Oxygen is one of the most commonly used drugs by anesthesiologists. The World Health Organization (WHO) gave recommendations regarding perioperative oxygen administration, but the practice of oxygen use in anesthesia, critical emergency, and intensive care medicine remains unclear. Methods We conducted an online survey among members of the European Society of Anaesthesiology and Intensive Care (ESAIC). The questionnaire consisted of 46 queries appraising the perioperative period, emergency medicine and in the intensive care, knowledge about current recommendations by the WH

Antiviral activity of Chongkukjang extracts against influenza A virus in vitro and in vivo

Bai Wei, Se-Yeoun Cha, Min Kang et al. · 2015 · Journal of Ethnic Foods

Chongkukjang is a traditional Korean fermented product prepared from soybeans and reported to have multiple biological functions, including antidiabetic, antiinflammatory, and neuroprotective effects. Influenza is a respiratory disease caused by influenza viruses and continues to be a worldwide threat with a high potential to cause pandemics. Besides vaccination, only two classes of drugs are available for antiviral treatment against these pathogens. We tested the inhibitory activity of an ethyl acetate extract from Chongkukjang toward influenza A virus neuraminidase. All 10 compounds extracte

Emerging biologic frontiers for Sjogren’s syndrome: Unveiling novel approaches with emphasis on extra glandular pathology

Xiao Li, Maierhaba Maitiyaer, Qing Tan et al. · 2024 · Frontiers in Pharmacology

Primary Sjögren's Syndrome (pSS) is a complex autoimmune disorder characterized by exocrine gland dysfunction, leading to dry eyes and mouth. Despite growing interest in biologic therapies for pSS, FDA approval has proven challenging due to trial complications. This review addresses the absence of a molecular-target-based approach to biologic therapy development and highlights novel research on drug targets and clinical trials. A literature search identified potential pSS treatment targets and recent advances in molecular understanding. Overlooking extraglandular symptoms like fatigue and depr

Deep brain stimulation for psychiatric disorders: role of imaging in identifying/confirming DBS targets, predicting, and optimizing outcome and unravelling mechanisms of action

Dejan Georgiev, Harith Akram, Marjan Jahanshahi · 2021 · Psychoradiology

Following the established application of deep brain stimulation (DBS) in the treatment of movement disorders, new non-neurological indications have emerged, such as for obsessive-compulsive disorders, major depressive disorder, dementia, Gilles de la Tourette Syndrome, anorexia nervosa, and addictions. As DBS is a network modulation surgical treatment, the development of DBS for both neurological and psychiatric disorders has been partly driven by advances in neuroimaging, which has helped explain the brain networks implicated. Advances in magnetic resonance imaging connectivity and electrophy

Predictors of Hospital Mortality in Patients with Acute Coronary Syndrome Complicated by Cardiogenic Shock

Gábor Szabó, András Ágoston, Gábor Csató et al. · 2021 · Sensors

As demonstrated by earlier studies, pre-hospital triage with trans-telephonic electrocardiogram (TTECG) and direct referral for catheter therapy shows great value in the management of out-of-hospital chest pain emergencies. It does not only improve in-hospital mortality in ST-segment elevation myocardial infarction, but it has also been identified as an independent predictor of higher in-hospital survival rate. Since TTECG-facilitated triage shortens both transport time and percutaneous coronary intervention (PCI)-related procedural time intervals, it was hypothesized that even high-risk patie

Entrepreneurial Skills, Significant Differences between Serbian and German Entrepreneurs

Carlos Morales, Percy Marquina Feldman · 2013 · Journal of CENTRUM Cathedra (JCC) The Business and Economics Research Journal

An extensive literature review reveals various authors acknowledge skills have an impact on entrepreneurial success. However, a lack of consensus regarding the main skills an entrepreneur needs is apparent. In this study, a contribution is made to the debate with empirical data and analysis, in two steps: by testing mean differences and reducing data with a principal components analysis. A sample of 394 potential entrepreneurs was administered the SAT-ECENT questionnaire, testing four skills: readiness to change, learning capacity, impact on people, and stress tolerance.

A Cognitive Approach to the Instruction of Phrasal Verbs: Rudzka-Ostyn’s Model

Ghuzayyil Mohammed Al-Otaibi · 2019 · Journal of language and Education

English as a Foreign Language (EFL) learners find some phrasal verbs problematic because of their idiomatic and polysemous nature. They are frequently used in spoken English and textbooks suggest an arbitrary way in teaching them. Cognitive linguists proposed that the particle plays a major role in determining the meaning of such phrasal verbs. This study investigated the effectiveness of a cognitive approach (i.e., Rudzka-Ostyn’s Model) in teaching taught and new phrasal verbs including metaphorical ones. Using a list of frequent phrasal verbs, a quasi-experimental design was used in which an
